Battery sharing system

Abstract

A battery sharing system is disclosed in the present invention. The system includes a number of rechargeable battery packs, at least one charging device and a monitoring device. A portion of rechargeable battery packs are provided to users for use under a sharing mode. When one used rechargeable battery pack is in low status, the user exchanges the used rechargeable battery pack with another one of the rechargeable battery packs which is fully charged.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a battery system. More particularly, the present invention relates to battery sharing system which can provide healthy and fully charged rechargeable batteries by verifying a battery status.BACKGROUND OF THE INVENTION[0002]With the improvement of production technology of the rechargeable battery and popularization of environmental protection and power saving in daily life, lithium rechargeable battery packs have gradually replaced traditional lead-acid batteries and become the power source for large electric vehicles or electric motorcycles. Inevitably, those rechargeable battery packs have the below operating problems: large size, high price and takes longer time to charge. Large size would cause difficulty to disassemble for repair. High price may make people hesitate to buy, and possibly have a higher chance of being stolen. Long period charging time requires electric vehicle manufacturers to provide more charging devic...

AI Technical Summary

Benefits of technology

[0019]Preferably, the user pays for the cost between the two exchanged rechargeable battery packs.

[0020]The battery sharing system provided by the present invention can effectively work and process monitoring by bringing the rechargeable battery packs into the operation of the system. It adopts a sharing mode to conduct exchange of rechargeable battery packs to achieve fast charge. Therefore, the demands above can be fulfilled.

Problems solved by technology

Inevitably, those rechargeable battery packs have the below operating problems: large size, high price and takes longer time to charge.

Large size would cause difficulty to disassemble for repair.

High price may make people hesitate to buy, and possibly have a higher chance of being stolen.

However, detailed studies on such battery exchange system reveal the troubles in operation.

First, if electric vehicles in a brand (system) have unified specification on the rechargeable battery packs that they use, the rechargeable battery packs might not able to be used by electric vehicles in other brand (system).

That causes waste of resources.

Meanwhile, the related costs are borne by the users.

If the rechargeable battery pack is not well monitored, the exchanged rechargeable battery pack might possibly fail accidently.

Another problem is how to manage rechargeable battery packs of different ownership.
